La Belle Dame Sans Merci Versions of Reality Quotes

How we cite our quotes: I cite by line number only.

Quote #1

The knight seems almost ghost-like in these first lines. The speaker finds him all "alone" and "loitering" near a lake. He's pale like a ghost, and the "loitering" seems like a ghost that haunts the place where he died.

Quote #2

I see a lily on thy brow With anguish moist and fever dew (lines 9-10)

The speaker can tell that the knight has a fever. High fevers can cause hallucinations or visions. Is it possible that the knight is just a sick man who had a feverish dream about a fairy lady who seduced him and then ditched him?
